The cork .is perforated longitudinally to re .cei ve the tube. L, through which the iuilk is drawn, and which-is 'held firmly in place by the compression of the rubber cork K as it is,

pressed into-the. mouth J of the bottle. The

Fig.3. 1 V The nipple is madein two parts, amoutli- 'piece, N, and a neck, 0. Themouth-piece N 'is made in the shape of the upper "part of an:

ordinary nipple, orin any other suitable shape,

andw-itli the rubber of about the same-thickness as the rubber in 1' an 'ordinal'y'nipple.

Around the inner surface of the open lower end of the mouth-piece Nisforzned-e, bead; Rto intel-lock with abead, Q, formed around the. outer;v surfeceofithe upper eud'of theneck O. :The

. neck 0 is formedof thicker rubber than the mouth-piece N, so that it will retain a tubular iiorm and will hold thelower eudof themout'hpiece N distended; It is aglass .QOllar or oouplingywhich has a bead, S, arouudits slightly.-- flariug'upper endto receive and holdthe lower eudiof the neck 0 and a bead, 4T, aroundits lower part to receiveund hold'th'e upper end-.-
